Are levels of digestive enzyme activity related to the natural diet in passerine birds?
(SOC BIOLGIA CHILE, 2011)
Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence ...
Physiological approach to explain the ecological success of 'superclones' in aphids: Interplay between detoxification enzymes, metabolism and fitness
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-02-26)
‘Superclones’ are predominant and time-persistent genotypes, exhibiting constant fitness across
different environments. However, causes of this ecological success are still unknown. Therefore, we
studied the physiological ...
Membrane-bound intestinal enzymes of passerine birds: Dietary and phylogenetic correlates
(2011)
Bird species exhibit great diversity in digestive tract morphology and enzymatic activity that is partly correlated with the chemical composition of their natural diets. However, no studies have assessed whether the ...
Comparison of immunofluorescence, enzyme immunoassay and cell culture for the diagnosis of Chlamydia trachomatis in urogenital infections Comparación de la inmunofluorescencia, ensayo inmunoenzimático y cultivo celular para el diagnóstico de Chlamydia tra
(1991)
We evaluated the usefulness of the direct immunofluorescence test with monoclonal antibodies and the enzyme immunoassay in comparison with isolation in cell cultures for the diagnosis of Chlamydia trachomatis in 55 ...
Enzyme or whole cell immobilization for efficient biocatalysis: focusing on novel supporting platforms and immobilization techniques
(Corporación Universidad de la Costa, 2021)
Effect of foliar nutrients, fungicides, temperature and metal ions on pectate lyase and endopolygalacturonase from Alternaria alternata found in association with sooty molds on Citrus trees
(Asociación Latinoamericana de Fitopatología, 1993)
The properties of pectate lyase and endopolygalacturonase, produced by Alternaria alternata isolated from sooty mold infected Citrus trees were studied. These enzymes, related to plant pathogenesis, were obtained from ...
Cell membrane regionalization in early mouse embryos as demonstrated by 5'-nucleotidase activity
(1982)
The distribution of 5'-nucleotidase activity in pre-implantation mouse embryos is studied by means of a cytochemical method adapted from Uusitalo & Karnovsky (1977). The enzyme activity is detected from the 4-cell stage ...
Efecto de la inhibición de la síntesis de angiotensina II en el consumo de alcohol
(SOC MEDICA SANTIAGO, 2008-08)
Background: Central renin-angiotensin system modulates alcohol intake and inhibition of angiotensin converting enzyme reduces ethanol consumption in rats, and may be potentially useful in the treatment of alcoholism. Aim: ...
Pompe disease: Clinical perspectives
(Dove Medical, 2017)
Pompe disease (acid alpha-glucosidase deficiency, OMIM 232300) is a rare lysosomal storage disorder due to autosomal recessive mutations in the GAA gene. It has also been called acid maltase deficiency and glycogen storage ...
Metabolic cost of osmoregulation in a hypertonic environment in the invasive African clawed frog Xenopus laevis
(Company of Biologists Ltd., 2016)
Studies of aquatic invertebrates reveal that salinity affects feeding and growth rates, reproduction, survival, and diversity. Little is known, however, about how salinity impacts the energy budget of vertebrates and ...
